| contents | We consider a stochastic dynamic game where players have their own linear state dynamics and quadratic cost functions. Players are coupled through some environment variables, generated by another linear system driven by the states and decisions of all players. Each player observes his own states realized up to the current time as well as the past realizations of his own decisions and the environment variables. Each player (incorrectly) believes that the environment variables are generated by an independent exogenous stochastic process. In this setup, we study the notion of ``subjective equilibrium under beliefs of exogenous uncertainty (SEBEU)'' introduced in our recent work arXiv:2005.01640. At an SEBEU, each player's strategy is optimal with respect to his subjective belief; moreover, the objective probability distribution of the environment variables is consistent with players' subjective beliefs. We construct an SEBEU in pure strategies, where each player strategy is an affine function of his own state and his estimate of the system state. |
